NKK Switches'JWMW and JWLW series are IP67 rated panel sealed rocker switches with TV ratings. The smaller JWMW series features a panel cut out of 25 X 15.4 mm and is certified for TV-5. It has an electrical capacity of 10A @ 125/250V ac resistive and 10A @ 30V dc. Larger JWLW devices have a panel cut out of 30.7 X 20.5 mm and are TV-8 rated with an electrical capacity of 16A @ 125/250V ac and 5A @ 72V dc. † JWLW devices are well suited as power distribution switches for telecommunications applications. The series' capabilities exceed a 160A inrush load. These devices have an exterior seal covering the flange that is an integral part of the switch. They are rated to IP67 of IEC60529 standard, which is similar to NEMA 4 and 6. An optional watertight boot is also available. Featuring UL, CSA and VDE approvals, JWMW and JWLW switches also carry a flammability rating of UL94V-0. † All JW rocker switches are constructed for dust resistance with an interior polyphenylene sulfide seal between the actuator and contact area. These devices also feature prominent external insulating barriers which increase the insulation resistance and dielectric strength. JW housings and cases are polyamide, a heat resistant resin meeting UL's 94V-0 standards. The solder lug/quick connect terminals are molded in and epoxy sealed to lock out flux, dust and other contaminants. The terminals are also specially designed to break light contact welds and can be used with connectors. † Design engineers can configure SPST, SPDT, DPST or DPDT circuits. All single throw models can be ordered with the international inscriptions for ON and OFF. These can be specified in vertical or horizontal orientation to accommodate any panel placement needs. JW devices include an integral rocker cap available in color options of black, gray, ivory or red. Housings can be specified in black, gray or ivory.
The National Highway Traffic Safety Administrationís recent backup camera mandate could open the door to more vehicle innovations, including better graphical displays, 360-degree camera views, and the increased use of Ethernet.
With support from National Instruments, a group of dedicated students from Connally High School in Austin, where more than 50% of the students are at risk of not graduating, have created a successful robotics team that is competing in the FIRST World Championships.
